Electronic Seven Day Time Switch

OWNER/ INSTALLER INSTRUCTION MANUAL
ATTENTION: READ CAREFULLY BEFORE ATTEMPTING TO INSTALL YOUR INTERMATIC
TIMER! FAILURE TO COMPLY WITH INSTRUCTIONS COULD RESULT IN PERSONAL INJURY
AND/OR PROPERTY DAMAGE! RETAIN FOR FUTURE REFERENCE.
The Intermatic Model ET716CK is an Electronic
Seven Day TIme Switch with Photo Sensor Enable.
Loads can be automatically switched ON or OFF
according to a programmed schedule, providing
appropriate light levels exist. The Photo Enable function ensures that loads are ON only if the ambient light
level is low enough to require lighting and only if the
user programmed schedule is switched ON. This timer
is not designed to directly switch loads over 5 amps or
tungsten (lamp) or other high inrush loads. The program will allow up to 28 set points (14 ON/14 OFF)
with up to 196 set points by using repeat daily cycling
for a seven day schedule. The photo sensor assembly
includes a sliding bracket which can be adjusted to
partially shield the photo cell, thereby increasing the
light level at which the load will switch ON and OFF.
The photo sensor can be located up to 1,000 feet from
the electronic time switch using ordinary 18 AWG bell
wire.
CAUTION: Connections made to the photo sensor
inputs, must be made outside of the enclosure and
made using UL listed 14 to 18 AWG wire. DO NOT
apply power to the photo sensor inputs.

Consists of photo cell light sensor. DO NOT apply
power to this sensor. Use only the supplied photo
sensor with the ET716CK time switch.
HOUSING: Completely sonic welded Lexan case.
WIRING: 2-12” Wire leads provided; additional low
voltage wiring for remote installations is required.
PHOTO SENSOR ACTIVATION: 2 to 15 FC “ON” and
2 to 15 FC “OFF” without the use of the sliding bracket. A built in hysteresis of 10% minimum ensures that
the ON and OFF switching levels are not the same.
REPLACEMENT PHOTO CONTROL ONLY: Order

General Safety Information
WARNING: Disconnect all power before installing or
servicing this timer or its connected loads.
1. Follow all local electrical and safety codes, as well
as the National Electrical Code (NEC), and the
Occupational Safety and Health
2. If the power disconnect point is out of sight, lock it
in the “OFF” position and tag it to prevent unexpected
application of power
This timer must be grounded.

4. Do not exceed the maximum current carrying
capacity of this timer
Always replace the plastic insulator covering the

1. Remove the mechanism from the case by depressing
the catch at the top of the case and pulling out. (See
Fig. 2) CAUTION: DO NOT TOUCH CIRCUIT BOARD
COMPONENTS.
2. Mount the timer in the desired location (three holes for
mounting are located on the back). (See FIg. 1).

tion.(Do not use aluminum wire.) Insert the wire ends
under the proper terminal plates and tighten the
screws firmly. (See Note Below)
6. Locate photo sensor timer input lead (large black cable
at bottom of terminal strip). Strip leads and connect
directly to photo cell or to connecting bell wire (14-18
AWG). Up to 1,000 feet of bell wire may be
used.
CAUTION: make all photo sensor connections
outside of the enclosure.
7. Replace the plastic insulator
8. Be sure that the battery clip is connected to the battery.
The batteries are factory installed.
9. Place the selector switch in the “MAN” position.
10. Re-apply power to the timer.
11. Wait until the display is lit steadily, then press “RESET” for two seconds. The display will now show: 1’10:00. The timer is now ready
for programming.
NOTE:
For inductive loads (lighting contactors, relays, etc.), it is necessary to install a surge suppressor across the time switch contacts. The
surge suppressor selected must be of the same voltage as the load (contactor or relay coil) being controlled. Use Intermatic part
number as follows:
176ET8A for 24 volt nominal loads - marked 8A
176ET9A for 120 volt nominal loads - marked 9A
176ET10A for 240 volt nominal loads - marked 10A
176ET22A for 277 volt nominal loads - marked 22A
Where excessive electrical noise is generated elsewhere in the load circuit an isolation relay may be required in addition to the surge suppressor or additional surge suppressors may be required on external contacts.
STEP 1. Insert load wire under one side of pressure plate and insert surge suppressor lead under other side of pressure plate.
STEP 2. Securely tighten the terminal screw.
Be certain that the body of the surge suppressor is at least 1/2 inch from the timer switch case. Insert surge suppressor(s) across each contact switching an inductive load. Do not use surge suppressors on both the normally open and normally closed side of the same output relay.

General Information (See Fig. 3)
MODE SELECTOR switch has four settings:
“MAN” -The automatic operation is bypassed while in
this position. Load(s) can be manually switched “ON”
or “OFF”.*
“AUTO”-Normal position for automatic operation.
Load(s) can be manually switched “ON” or “OFF”. The
timer will resume automatic operation beginning with
next set point.*
the
“SET”-T
“REVIEW”-To check the program, or clear entries for
program modification.
ON INDICATOR LIGHT:*
Flashes when the selector switch is set in “REVIEW”
or “SET”.
Glows steadily when normally “open” contacts are
“closed” during automatic or manual operation.
Does not glow when normally “open” contacts are
“open” during automatic or manual operation.
RESET BUTT
Resets the microprocessor before programming or to
erase the entire program.
CLEAR BUTTON:
Clears the displayed entry in “SET” or “REVIEW”.
CLOCK BUTTON:
Sets the time of day.
AND OFF BUTT
ON
To enter programming steps for “ON/OFF” set points as well as manually controlling the loads.
*NOTE: If the photo sensor has been connected the load will not switch ON unless darkness is sensed. To check the wiring, tempor-
arily disconnect the photo sensor from the time switch. This will allow the load to be switched ON, regardless of the ambient light
level, by pressing the ON keypad in either MAN or AUTO modes. A built in time delay may cause up to a 2 minute response delay to
sudden changes at Photo Sensor input.
